1. Gadgets galore: Want to learn how to pick a lock? See how a 3-D printer works? Try on something called a “robomustache?”

Those are among the many activities at this year’s Maker Faire North Carolina, an annual festival that showcases “makers” of all stripes who are bringing their ideas to life at kitchen tables and in garage workshops. The event lets visitors get hands-on with the unusual creations. 10 a.m. to 6 p.m. Saturday, State Fairgrounds Exposition Center, $10 for adults and $5 for kids 12 and younger, makerfairenc.com.

2. The coast comes downtown: Get a taste of North Carolina’s best seafood dishes in Moore Square on Saturday.

Chefs and fishermen from Raleigh, the Outer Banks and Jamaica are teaming up for N.C. Fresh Catch Raleigh. They’ll be fixing up OBX clambake, island-style fish ‘n’ chips and Jamaican peppered prawns as local artists hawk their wares and diners relax with live music that spans genres from reggae to country. Admission is $4, but the price is credited toward your first food or beer purchase. 1 to 7 p.m. Saturday, Moore Square, ncfreshcatch.com.

3. Theater on the move: Downtown’s entire Warehouse District becomes a stage during First Friday.

The audience for Moving Pieces: A Multi-Venue Traveling Theatre Experience follows the characters through art galleries and alleyways, the action blending into the bustle of First Friday. The crowd stays connected through a group text message that also lets the audience pick the ending. Space is limited and last month’s performance sold out. 6:30 and 8:30 p.m. Friday, starting from Cafe De Los Muertos, 300 W. Hargett St., $20, movingpiecesraleigh.com.
